BER'I'I-I MOUNTING.

Application filed April 2, 1925.

To all whom it may concern:

Be it known that we, EMIL Nrsnol and EMIL NYMAN, citizens of Finland,residing at Hoquiam, in the county of Grays Harbor and State ofIVashington, have invented certain new and useful Improvements in BerthMountings, of which the following is a specification, referencebeing'had to the accompanying drawings.

This invention relates to mountings for ships7 beds or berths and moreparticularly to a mounting so constructed as to elminate strain of thebed and to maintain the bed at all times in horizont-al position.

A further and more specific object of the invention is the improvementof gimbal joint structure employed for supporting the bed enabling theproduction thereof at a moderate rate while at the same time increasingthe rigidity of the structure.

These and other objects We attain by the construction shown in theaccompanying drawings, Wherein for the purpose of illustration is showna preferred embodiment` of our invention and whereiiu- Figure 1 is aperspective view of a berth supported in accordance with our invention;

Figure 2 is a vertical sectional view through the gimbal joint;

Figure 3 is a perspective of the cross bars of the gimbal joint; and

Figure 4- is detailed sectional view showing the mounting of thesupports for the bed upon the gimbal joint.

Referring now more particularly to the drawings, the numeral 10indicates a Ceiling attached support in the form of an inverted U, thecentral portion of which is rigidly secured to a hanger 11 which is inturn rigidly secured to the ceiling 12, as at 13.

The ends of the arms of the U-shaped support engage with pivots 111formed by directing through a gimbal ring 15 a bar 16 which is circularin cross section and of sufficient length to project beyond the sidefaces of the ring. rI`his bar has its under surface notched, as at 17,for the passage of an oppositely notched similar bar 18, the ends ofwhich likewise project beyond the ring 15 and are formed with pivots 19for the reception of supports 20 for a bed 21. It Will be obviousv thatthe universal movement provided by the gimbal ring and its connection tothe supports 10 and 20 will permit the bed at all times to rema-in inhorizontal position regardless of the angle which is assumed by SerialNe. 20,253.

the vessel in which the berth is arranged. Particular attention isdirected to the construction of this gimbal ring.V The bars 16 and. 18connected to: the uppor and lower supports respectively are notched upontheirl under and upper faces respectively to permit their passage and atthe same time permit use of a straight bar.

It Will be obvious that strain of weight supported from the ring uponthe ends 19 of the bar 18 will tend to flex the center of this barupwardly and with the weight of the ring itself and of this load Whichis applied to the outer ends or pivots 14 of the 'bar 16 will tend tofiex the center of the bar 16 downwardly. `I1`hese bars will, therefore,tend to flex in opposite directions with substantially equal forces,oifsetting the stress Which s placed thereon and thereby permitting theuse of lighter bars 16, 18, that could otherwise be employed.Furthermore, the interengagement of these bars at the notches thereofWill elfectually prevent longitudinal Shifting of either of the bars andthe pivots 14 and 19 Will, therefore, always be properly projected forengagement with their respecring and having notched engagement one` withthe other, the ends of said bars projecting to provide pivots forengagement With the respective supports.

2. In a support for ships7 berths, a support adapted to be engaged Witha ceiling and embodying spaced arms, a second support havinn" spacedarms secured to the berth and projecting upwardly therefrom, and agimbal ring structure for connecting said supports comprising a` ring,bars extending at right angles an'd diametrically of said ring andhaving notched engagement one with the other, the ends of said barsprojest-ing to provide pivots for engagement With the respectivesupports, the bar the ends of Which is engaged With the Ceiling attachedsupport being notched upon its under surface, the bar engaged With theberth support being notched upon its upper surface Whereby strainsapplied to either of said bars tend to flex the bar from the other ofthe bars.

3. In a support for ships7 berths, a support adapted to be engaged witha Ceiling and elnbodying spaced arms, a second support having spacedarms secured to the berth and projettin: v rgwardiy therefroin, and agiinbai ring structure for connecting said supports eonoprisin;v a ring,crossed dainetricaily extending bars carried by said ring and With Whichthe ends of said arms are enoaged, said bars having engagenient one Withthe other Whereby each opposes flexure of the other upon the applicationof Weight to said supports through the ring.

In testlnony Whereof we hereunto affix our signatures.
